MOBILE TELEPHONE HOLDING DEVICE
The present invention relates to a mobile telephone holding device which includes a main body, an arm, at least two clamping elements, a wireless electrical charging device with which a mobile telephone can be charged and an electrical switching device, wherein the arm s mounted on the main body in such a way that the arm can be moved between an inoperative position (R) and at least one holding position (H) against a restoring force, wherein the electrical switching device, depending on the position of the arm, interrupts an electrical line which leads to the charging device in the inoperative position (R) of the arm, and closes the electrical line which leads to the charging device in each holding position (H) of the arm.
1. Field of the Invention
The present invention relates to a mobile telephone holding device.
2. Description of Related Art
DE 10 2011 110 680 A1 discloses a mobile telephone holding device which comprises a wireless electrical charging device and into which mobile telephones of different dimensions can be inserted.
SUMMARY OF THE INVENTIONThe object of the present invention is to propose a mobile telephone holding device which is energy-saving and prevents unnecessary electromagnetic radiation in the vehicle interior.
In the mobile telephone holding device according to the present invention, the charging device or the charging device and a cooling device are supplied with power only when a mobile telephone is actually inserted into the mobile telephone holding device, wherein the presence of a mobile telephone is detected in a simple manner by the position of the arm with which the mobile telephone is clamped into the holding means. The consumption of power by the charging device or the charging device and the cooling device can be reduced in a simple manner by mechanically ascertaining the presence of a mobile telephone in this way. Furthermore, the creation of electromagnetic radiation is also avoided as a result, the electromagnetic radiation always occurring when charging devices, by virtue of activation of their charging coils, test whether a device which is to be charged is inserted.
By virtue of designing the arm as a movable sliding carriage, it is possible to match the mobile telephone holding device to mobile telephones of different sizes in a simple manner.
If two of the clamping elements are connected to the arm and two of the clamping elements are connected to the main body, it is possible to hold the mobile telephone at four corners and in this way to reliably prevent the clamping elements acting on buttons of the mobile telephone which are arranged around the edge of the mobile telephone.
As an alternative, provision is made to connect one of the clamping elements to the arm and to connect two of the clamping elements to the main body. In this way, the mobile telephone is reliably clamped into the holding device at three points.
Provision is further made to assign one switch to the arm, wherein the switch is, in particular, in the form of one of a microswitch, an optical switch and a sensor, in particular, in the form of a Hall sensor, wherein the switch is operated in the inoperative position of the arm in such a way that the electrical line is interrupted and therefore a power supply is interrupted, and that the switch is operated in each holding position of the arm in such a way that the electrical line is closed and therefore a power supply is established. The mobile telephone holding device can be produced in a convenient manner by virtue of the use of a microswitch. The use of an optical switch or other sensors makes the mobile telephone holding device particularly insensitive to vibrations since moving components are dispensed with in this case.
By virtue of designing the main body of the mobile telephone holding device with a base, it is possible to arrange the mobile telephone holding means in a cupholder, which is present in a motor vehicle, in a secure and reliable manner, so that the mobile telephone holding means can be used without a special holding means being fitted.
Provision is further made to equip the cooling device with at least one of a fan and a Peltier element. In this way, the mobile telephone and/or the charging device can be cooled in a simple manner, so that the situations of the mobile telephone and the charging device reaching impermissible temperatures and being undesirably switched off for safety reasons are prevented. According to further design variants, provision is also made, as an alternative or in addition to the at least one of the fan and the Peltier element, to provide at least one heat pipe on the charging device as the cooling device, heat being dissipated from at least one of the charge-receiving device of the mobile telephone and the charging device of the holding device by the heat pipe.
Finally, provision is also made to arrange the cooling device adjacent to at least one of the charging device of the mobile telephone holding device and the charge-receiving device of the mobile telephone. The local proximity to the at least one of the charging device and the charge-receiving device ensures effective cooling.
Further details of the present invention will be described in the drawing with reference to schematically illustrated exemplary embodiments.
